CAT2300 is a controller for MOSFET current monitoring in high-side switch applications. CAT2300 provides current mirroring and ON/OFF control for MOSFETs. Exact control and matching of the Sense output of the MOSFET with the Kelvin voltage insures accurate current monitoring over a couple of decades of current. CAT2300 is the single chip alternative to discr.
